Pick style and length, then generate sci-fi planet names
A sci-fi planet name generator produces proper nouns for worlds on your star chart — either invented syllable blends or survey-style catalog strings readers recognize from hard science fiction.
Use it when you need many labels fast: sector maps, chapter headers, game placeholders, or concept art briefs. Output is fictional and for creative use, not verified astronomical data.
Three quick steps from blank star chart to usable proper nouns.
Choose how many planet names you need — up to fifty per generation.
Exotic, mythic, harsh, or catalog; short, medium, or long for invented styles.
Roll names instantly and copy the full list as plain text, one per line.
What each option changes in your generated planet names.
Soft alien syllables from 25 starts, 18 mids, and varied ends — optional Prime or Minor suffixes.
Classical and stellar cadence — 19 starts, 10 mids, 9 ends including Major and Ascendant tags.
Aggressive consonant clusters — 16 starts, 12 cores, apostrophe variants, Prime or roman-numeral flavor.
Survey families: HD/HIP/HR/TYC numbers, Kepler-, Gliese, WASP-, TOI-, LHS, TRAPPIST-1 letter worlds.
Short, medium, or long syllable stacks for invented modes; catalog follows survey patterns automatically.
Up to fifty names; optional duplicates off for distinct rows until the pool exhausts.
Style, length, volume, and duplicate behavior.
Four philosophies — lush invented, mythic, hostile, or bureaucratic survey strings.
Disabled for catalog; controls syllable depth for exotic, mythic, and harsh generators.
Fifty-name batches for sector maps; unique mode for anthology variety.
When to pick invented phoneme blends for dialogue and tone.
Pronounceable in dialogue — Voara, Aerion Prime, Stellara — colony nicknames come easy.
Kraxyth, Vlok Prime — implies volcanic atmospheres, militant stations, or frontier hazard.
Kepler-442b, Gliese 581 e — fleet logistics, hard-SF charts, and settler bureaucracy tone.
Fictional strings weighted across familiar astronomical naming patterns.
Numeric catalog strings with optional letter suffixes — familiar stellar survey flavor.
Mission-style prefixes with planet letter designations for colonized systems.
Transit and nearby-star naming patterns for modern exoplanet discovery tone.
Label worlds here, then flesh them out in the World Building Generator for cultures, magic or tech systems, and conflict hooks. Use Story Plot when a named planet needs a mission arc.
Catalog names suit fleet charts; exotic and mythic names suit what characters say aloud — you can assign both to the same world.
Three layers after you copy planet names into your project.
Fill a sector column — star three favorites before you write climate or politics.
Capital, prison moon, garden world — one line per name so prose stays consistent.
Open World Building Generator for culture, conflict, and system hooks on the winner.
Built for rapid iteration while you outline sectors and navigation lore.
Exotic, mythic, harsh, and catalog — swap tone per faction or survey authority.
Invented styles mix dozens of tokens — not a fixed list of twelve planet seeds.
Weighted random among HD-style, Kepler, Gliese, WASP, TOI, LHS, and TRAPPIST patterns.
Populate hex crawls, procedural galaxies, and classroom prompt sheets in one click.
Reduce repeats within a batch when you need variety for adjacent worlds.
One-click copy to docs, Notion, spreadsheets, or campaign wikis — no upload.
Writers and designers reach for planet generators throughout a project lifecycle.
Star charts and chapter headers without slowing drafting momentum.
Hex crawls, sector maps, and traveler sandbox tables.
Placeholder planet strings before lore and biome passes.
Constraints for flash fiction and anthology submissions.
Labeled target worlds before architecture and atmosphere design.
Speculative setting prompts with science literacy hooks.
Mix tones so every world feels intentional on your star map.
Alphanumeric discipline readers associate with hard SF and fleet paperwork.
Exotic and mythic modes stay alien yet speakable in dialogue.
Harsh modes signal danger before you describe atmosphere or factions.
Search-aligned notes for choosing the right naming mode.
This tool labels worlds; World Building supplies cultures, conflicts, and system hooks.
Catalog suits Terran bureaucracy; exotic/mythic suit settler nicknames and local honorifics.
Survey strings mimic real conventions but are not verified ephemeris — safe for creative use.
Quick definitions for writers and GMs landing from search.
A bureaucratic planet label tied to a survey mission or star catalog — e.g. Kepler-186f style strings.
The capitalized name characters use in dialogue — may differ from the official catalog string.
Syllable chunks combined randomly to produce invented alien names.
Turn a random label into a destination readers remember.
One line on temperature and storms keeps slang grounded after you pick a name.
Tidally locked worlds, belt habitats, and rogue planets imply different governance — use or subvert.
Favor exotic or mythic modes for audible dialogue, or gloss harsh names once.
Similar strings need settler nicknames so readers tell planets apart.
Same catalog label can mean Terran bureaucracy or a local honorific — different story.
Pick names that allow moons, megastructures, or gate suffixes in later books.
Planet names — styles, catalog, batch, fiction use, and privacy.
